I personally think we will see far more of Rodri pushing on when playing with Kovacic, Rodri is more than capable of scoring a decent amount of goals, superb shot on him and very good in the air.Kovacic will be different as he will be running forward with the ball in tight areas looking for a 1-2 on the edge of the box which will get the opposition pulled out instead of being camped in the box.
You can already see he has complete trust in Kovacic.
